As large-scale text and data mining (TDM) becomes more common in multiple fields, you may look to the library's databases to access data. We have many different databases, some of which contain materials that are in the public domain or are no longer under copyright, while others are still under copyright protection.
In addition to copyright considerations, we must take into account what the database vendors’ own policies specify in regard to this type of use. When providing access to a database, the library enters into licensing agreements, which also dictate what types of data can be extracted and used.
If you are thinking of basing a research project on data extracted from a library database, please contact a business librarian to discuss issues around permissions (copyright and licensing agreements), formats and fees.
